High S/N Mg II profiles line_4: will be acquired to search for discrete absorption features line_5: superposed on the emission lines. LSA and SSA observations line_6: using echelle B and G270M are made to allow experiments with line_7: deconvolution of LSA and medium resolution data. ! ! end of abstract general_form_proposers: lname: EBBETS fname: DENNIS mi: C. inst: BASG country: USA ! lname: CARPENTER fname: KENNETH mi: G. inst: NASA - GODDARD SPACE FLIGHT CENTER country: USA ! lname: ROBINSON fname: RICHARD inst: CSC @ NASA-GSFC country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: The following observations are made on Alpha Tau: line_3: 1. Ech-B LSA and SSA at 2325 A C II line_4: 2. G270M LSA and SSA at 2345 A C II/SI II/FE II line_5: 3. ECH-B SSA at 2799 A MG II ! question: 4 section: 1 line_1: The data required for this program consists of UV spectra not obtainable from line_2: the ground. IUE does not have the required wavelength resolution and line_3: S/N capability required to obtain the high precision line profiles and line_4: absolute velocities required for our program. ! question: 5 section: 1 line_1: line_8: An interactive acquisition is requested unless onboard acquisitions have line_9: been adequately validated before the execution of these observations. line_10: An onboard acquisition is included to be used if possible. ! question: 6 section: 1 line_1: ! question: 7 section: 1 line_1: The data will be reduced and analyzed primarily with in-house software line_2: developed for analysis of IUE data and with new software to be developed line_3: in-house. Software used during ground-based calibration of HRS at Ball line_4: Aerospace (Boulder, co) by the PI, will also be used in the reduction and line_5: analysis of these observations. ! question: 10 section: 1 line_1: See section 7. ! question: 12 section: 1 line_1: The target observed in this program is: line_2: Alpha Tau line_4: Kenneth Carpenter (301)-286-3453 is the line_5: principal contact. ! question: 13 section: 1 line_1: We plan UV spectroscopic observations (with GHRS) of the K giant Alpha Tau. ! !end of general form text general_form_address: lname: EBBETS fname: DENNIS mi: C. category: PI inst: BALL AEROSPACE SYSTEMS GROUP addr_1: @STSCI city: BALTIMORE state: MD zip: 21818 country: USA phone: 301-338-1437 ! lname: CARPENTER fname: KENNETH mi: G. category: CON inst: NASA-GODDARD SPACE FLIGHT CENTER addr_1: CODE 681 city: GREENBELT state: MD zip: 20771 country: USA phone: 301-286-3453 ! lname: ROBINSON fname: RICHARD inst: CSC @ NASA-GODDARD SPACE FLIGHT CENTER addr_1: CODE 681 city: GREENBELT state: MD zip: 20771 country: USA ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: HD29139 name_2: ALPHA-TAU descr_1: K5 III pos_1: RA=04H33M02.896S+/-0.1", pos_2: DEC=16D24'37.51"+/-0.1" equinox: 1950 pm_or_par: Y pos_epoch_bj: B pos_epoch_yr: 1950.00 ra_pm_val: 0.004333 ra_pm_unct: 0.000067 dec_pm_val: -0.1890 dec_pm_unct: 0.0010 rv_or_z: V=+54 fluxnum_1: 1 fluxval_1: V=0.84+/-.2,TYPE=K5 III fluxnum_5: 1 fluxval_5: F(2327)=3.E-12 fluxnum_8: 2 fluxval_8: F(2799)=8.E-11 ! ! end of fixed targets !
